This book contains the complete text of De Bello Gallico, Book I; an interlinear translation; and an accompanying, more polished translation are just part of this reference work. At the bottom of each page below the text, each Latin word is completely parsed and the commentary includes useful references to the revised grammars of Bennett, Gildersleeve, Allen and Greenough, and Harkness and delves into word derivations and word frequencies, making this volume helpful for the competent reader of Latin as well as the novice.
